Background: Colonoscopy has been proven effective diagnostic and therapeutic tool that can be useful in diseases of colorectal lesions. The purpose of this study is to pro- pose a robotic colonoscopy for patients infected by highly virulent contagious disease or patients in remote site where medical care is not possible.
Methods: A slave robot was developed to hold the colonoscopy instead of endosco- pist. This slave robot performs insertion, rolling motion, and two steering motions of the distal end of the fl exible endoscope. Also a master robot was developed to teach motions of the slave robot. In order to provide the endoscopist with haptic feeling, the insertion force and the rotating torque were measured and feedback to the master robot.
Results: The endoscopist performed the master-slave robotic colonoscopy using a colon phantom. One endoscopist and two engineers participated in the robotic colo- noscopy. The task completion time was comparable to conventional colonoscopy and gets decreased as they repeat the test. The haptic function was also helpful to feel the constrained force or torque inside colon.
Conclusions: This work proposed a robotic approach for colonoscopy and this robotic device would be effective to perform colonoscopy for patients in remote site.

Background: Malnutrition has been known to be associated with poor outcomes of hospitalized patients. Nutritional intervention is recommended for malnourished patient but the evidence is lacking. The purpose of this cohort study was to analyze the impact of nutritional interventions on nutritional status of patients admitted to gastroenterology.
Methods: We enrolled patients who were classifi ed as malnourished by SNSI (Severance Nutrition Screening Index) at Severance hospital. As nutritional intervention, we mod- ifi ed patient’s diet, provided oral nutrition supplement, and conducted diet education and counseling for 7 days. We evaluated the patient’s weight, body mass index (BMI), daily calorie and protein intake, handgrip strength, body cell mass, patient-generated subjective global assessment and biochemical parameters including albumin, choles- terol, total lymphocyte count (TLC) before and after nutritional intervention.
Results: From May 2014 to July 2014, 132 patients were classifi ed as malnourished.
Twenty two patients agreed with nutritional intervention. Among 22 malnourished patients, 16 patients completed nutritional intervention program. Handgrip strength (P<0.017) and maximal protein intake per day (P<0.045) were signifi cantly increased after intervention. In low BMI (<21) patients, handgrip strength (P<0.021) and maximal energy intake per day (P<0.049) and maximal protein intake per day (P<0.013) were signifi cantly increased after nutritional intervention (Table 1).
Conclusions: Nutritional screening and intervention were associated with improve- ment of nutritional status in hospitalized gastroenterology patients. Further analysis revealing impact of nutritional intervention program on the long term prognosis of patients admitted to gastroenterology is needed.
